Prolonged menstrual periods in perimenopausal women are mainly considered to be caused by ovarian hypofunction. Ovarian hypofunction and endocrine disorders may cause prolonged menstrual periods, menstrual cycle disorders and abnormal menstrual flow. This is a good age for gynecological tumors, so patients must undergo relevant examinations to exclude abnormal bleeding caused by gynecological tumor diseases. If the bleeding is simply caused by ovarian hypofunction, the patient can take the following methods for treatment: First, if the patient does not bleed much and no anemia occurs, she can choose to use Chinese herbal medicine for treatment, such as Kuntai capsule, deer fetus cream and other herbal medicines that nourish the kidneys, nourish the blood and benefit the qi, for menstrual cycle regulation. If herbal treatment is not effective, patients can choose to use estrogen and progesterone, such as tonic Jiale and progesterone, to stop bleeding and cycle regulation. Secondly, if the effect of medication is not good, patients can choose to have the intrauterine device Mannakil placed in the uterine cavity for treatment. Third, if the above treatment methods are not effective, patients can choose endometrial electrodesis or surgical removal of the uterus for treatment.
